The installation site should be a certain distance away from lathes, grinders and other mechanical equipment. The site should be cleaned and kept dry and clean at all times to prevent iron filings, sand, dust and moisture from entering the bearings.

Water-lubricated bearings refer to bearings that are used directly in water without any sealing device. The bearings are lubricated by water and do not require lubricating oil or grease, eliminating the harm of water pollution. Bearings are often used in flowing water, which can effectively control the temperature rise of the bearings, so that they have a long service life and are safe and reliable. The structure is suitable for horizontal, vertical and inclined axes.

The end face and inner and outer cylindrical surfaces of the bearing end cover require turning. Semi-finishing and rough turning can be used, and roughing and finishing should be carried out separately to ensure the surface roughness requirements. The main bearing end cover process design is as follows:

Hybrid ceramic bearings may be less common, and the main configuration of hybrid ceramic bearings is composed of inner and outer ring bearing steel/stainless steel + ceramic balls + PA66/stainless steel retainers + 2RS/ZZ. Hybrid ceramic bearings have the following four advantages during use.

To overcome the shortcomings of fire prevention in practical applications of bearing steel materials, fire prevention treatment must be carried out, the purpose of which is to increase the fire resistance limit of bearing steel to the limit range specified in the design specifications. There are many measures to prevent bearing steel from rapidly heating up and deforming and collapsing in a fire. The key is to adopt different methods according to different situations, such as using insulation and refractory materials to block the flame from directly burning the bearing steel, reducing the speed of heat transfer, delaying the time when the bearing steel temperature rises and the strength weakens, etc. But no matter what method is adopted, the principle is the same. The following introduces several fire protection measures for different bearing steels.
